Aviz Networks outlines Aviz Packet Broker 2.12.1 features

Aviz Networks released Aviz Packet Broker (APB) 2.12.1, adding dual-rate transceiver support for Broadcom platforms, hardware-accelerated packet length filtering, and expanded sFlow sampling controls. The update targets enterprise packet visibility and traffic-selection workflows in modern data centers.

Research Overview

The vendor brief describes APB 2.12.1 as a software release focused on optical deployment flexibility, more granular traffic filtering, and improved observability controls. It outlines new capabilities for transceiver behavior, packet selection by size, and sFlow sampling direction and interface-level enablement.

Key Findings

APB 2.12.1 introduces native dual-rate optics handling for compatible modules on Broadcom platforms, with an automated recovery mechanism after transceiver re-insertion. It also adds packet length rules enforced using hardware field processors and provides new CLI controls for sFlow sampling direction and polling interval management.

According to the post, dual-rate configurations persist across reboots, service restarts, and hardware replacement events. The release also states that packet length qualifiers can be combined with existing filtering criteria such as IP addresses, VLANs, protocols, DSCP values, and transport ports.

Technical Breakdown

The dual-rate transceiver feature is implemented through standardized RS0/RS1 register controls, enabling optics to operate at either 1G or 10G speeds. The brief also describes a background monitoring service that detects transceiver insertion events and automatically restores the configured operating mode.

For traffic filtering, APB 2.12.1 supports packet length rules on Broadcom Trident and Tomahawk platforms using hardware-accelerated field processors at wire speed. The post states that the platform can permit or deny packets based on predefined length thresholds and lists example use cases such as dropping jumbo frames from monitoring streams, forwarding only critical control-plane traffic, filtering fragmented or undersized packets, and mirroring large application flows to analysis tools.

Operational Impact

The sFlow updates add CLI controls to configure sampling direction either globally or at the interface level, with support for ingress, egress, or bidirectional sampling based on platform capabilities. The release also adds per-interface enable or disable controls for sFlow while preserving interface-specific configuration.

In addition, APB 2.12.1 includes improvements to sFlow polling interval management intended to streamline deployment and ongoing maintenance workflows. The brief emphasizes that dual-rate settings are integrated into the system configuration framework to preserve behavior across operational events.

APB 2.12.1 consolidates three areas—optical dual-rate handling, hardware packet length filtering, and expanded sFlow sampling configuration—into a single release aimed at operational control over traffic selection and observability.
